TOUGH +: Modeling Fluid and Heat Flow in Porous and Fractured Ground

Technology Marketing SummaryTOUGH+ is a general-purpose numerical simulation program for modeling multiphase fluid and heat flow through porous and fractured media. It is the successor to the TOUGH2 suite of codes developed at the Lawrence Berkeley National Laboratory (LBNL). Various modules can be linked to the core of TOUGH+ to describe different fluids and their compositions, or to simulate more complex, coupled processes.DescriptionTOUGH+ is designed for the analysis and prediction of geothermal reservoirs, nuclear waste storage sites, gas hydrate-bearing formations, geologic carbon sequestration sites, saline and freshwater aquifers (including the vadose zone), and sites contaminated by radionuclides or volatile organic compounds.Benefits
